Cloud Seeding in China

By: Jamie Campbell

In an effort to end a decade long drought in the Beijing area, the Chinese government has been experimenting with weather manipulation, with mixed results. While the government’s actions do seem to be having an effect, bringing some of the earliest snows on record to Beijing, they are both good and bad. The practice of cloud seeding, adding chemicals to the clouds that make them produce rain more readily, can increase precipitation by up to 20%. The chemicals, in most cases silver iodide, dry ice or liquid propane, can be delivered in a variety of fashions, from planes to China’s preferred method, rockets or artillery. But the results of this manipulation are not all good. The snowstorms have wreaked havoc on the people, traffic and infrastructure of Beijing. The snow causes roads to close, halting business, flights and classes. China is not the only government to experiment with these techniques. As of now, 24 countries practice some kind of cloud seeding, including the USA.

Cloud seeding and weather manipulation in general could have an enormous impact on our lives and our environment. Used responsibly, it could end droughts, stop floods, and redirect hurricanes and other dangerous weather to places where it won’t hurt humans. Unfortunately, this technology could be a most destructive weapon. Imagine, redirecting a hurricane towards an enemy, a hurricane that will release the energy of multiple atomic bombs. And even more, there would be zero accountability. There would be almost no way to prove who, or even if someone had attacked you.

At this point, I support weather manipulation. The benefits, if perfected would be enormous. Weather causes huge amounts of suffering, and used responsively, we can stop a large portion of it. While this technology could theoretically be used as a weapon, our skill is much too low to use it effectively. I feel that the befits of weather manipulation far out way the potential risks.

Getting Social...With a Virtual Homo Sapien?


Getting Social...With a Virtual Homo Sapien?
By: Lindsey Elizabeth Horton
Usually autistic kids aren't very involved with the enviroment around them. They can be incredibly smart, and have talents that non-autistic people wouldn't have, but they don't socialize very much. Yet, psychologist Justine Cassell and her collegues found that there was a solution that could possibly make autistic kids more socialable.

There was an exmperiment that was done with 12 pairs of children, ranging from ages seven to eleven. In the experiment, six pairs of children were put together where there was one autistic child per pair, with another child with no developmental complications. The other six pairs were all made of children with no developmental complications also. The challenge presented to the youngsters was to use a toy castle to show a story. First, with their actual partner, then with a virtual partner. The virtual partner was a 3-D version of a child who was designed for typcial conversation and reactions for that age group. The virtual kids were also designed to be patient with their partners, pause for responses, and give feedback to their partners. 

The results? Amazing! Autistic kids actually participated in making the story, and they also took turns in conversations, as well as thought of new story ideas with their virtual partners. They did all of this much better with their virtual friends, rather than their here and now, real partners. 

Cassell suggests that further investigation should be taken into regular exposure of autistic kids to virtual friends. The centeral idea here is that the regular exsposure would build skills in the autistic children that would then transfer to real people, and real relationships with other humans. I think that the impact on society would be very influental. It is observed that autistic people often have very neat talents. If these talents were paired with socialization skills, perhaps autistic people in general, especially youth, that are fresh with new ideas on the world, could show the rest of us, who don't all have access to unique minds such as they do, new and better ways to be inventive and smart in our lives. The world could be a better place, perhaps led into a new era by a different type of thought, inspired by the social relationships with autistic people, young and old alike. This significant future would be made possible by new experiments and edge breaking technology such as the one described above. 

I choose this article because I have met autistic people, who as kind and smart as they are, usually don't socialize with me much. I would love to be able to have a very in depth conversation with them on their thoughts of the world, and on day to day things in general. Such as school, homework, and modern technology. I love the thought of using all of a brain's potential, I mean after all, I do parshily want to be a cognative scientist! I think that autistic people really have something on unlocking areas that normal people can't. Can you imagine being able to unlock that potential in yourself? I sure can! They say that we only use about a percent of our brain, and look we have accomplished! Why not got another percent?!

Penguins and Sea Lions Help Produce New Atlas


By Samuel Mann

Atlases are usually made and used by people for navigation in parts of the world. They provide accurate information on latitudes, longitudes, water features like lakes and shorelines and terrain features like mountains and valleys that are important for pilots, sailors, or even simple hikers. What you wouldn't expect from an atlas is that is was not made by humans (so-to-speak). The Wildlife Conservation Society (WCS) and BirdLife International have released a new atlas of the Patagonian sea using data that was collected from 16 species of marine animals and produced 280,000 data entries! The Patagonian Sea is a huge body of water from southern Brazil to southern Chile.

The atlas contains the most accurate maps ever assembled for this ecosystem revealing key migratory corridors that span from coastlines to deep-sea feeding areas off the continental shelf hundreds of miles away. The project took 25 scientists 10 years to complete! The list of species tracked for the atlas includes five species of albatross, three species of petrel, four varieties of penguin, two fur seal species, the South American sea lion, and the southern elephant seal.

The significance of this new atlas is that not only was it written by the wildlife that inhabit the area, but it also records marine animal migrations and breeding patters that are important to take into consideration for conservation. This data will be important for managing fisheries and routes for oil tankers that protect important habitats for the marine animals. Conservation is an ever growing concern in life due to the degradation of the ecosystem. What better to preserve the ecosystem than to know just which habitats are the most crucial? This way mariners can plot courses through waters that aren't as vital or fragile.

I think that it is really creative to use the animals that live in an area to plot the land features such as deep water and shorelines. Various animal behaviors require that they travel to certain land features such as deep water feeding, coastal nesting, or perhaps breed grounds. Using GPS on marine animals not only shows their behavioral patterns but also maps out certain geographic features of previously unknown or unfamiliar locations. I think it is ingenious.

Geneticists Use DNA to Diagnose Patient


A team of researchers at Yale recently used DNA sequencing to diagnose a 5 month old patient.

He was suspected of having Bartter syndrome, a kidney problem that causes dehydration. The team sequenced the protein-coded portion of his dna, and found that he didn't have Bartter, but a mutation in his kidney that caused similar symptoms. The protein coded part of DNA is only 1% of all DNA, but it causes a large portion of genetic disorders and diseases.

This could change medicine forever. Doctors don't have to fit together a puzzle of symptoms and tests to guess at a disease. Instead, they can almost literally take a picture of the patient's DNA and know for sure what's wrong with them. Unfortunately, not all diseases can be found in DNA, only some of the genetic ones. Although limited, this has a lot of potential as well.

This article impressed me, I didn't know it was practical or eve possible to use DNA to diagnose patients. I'm interested to see how this will be implemented into medicine, and how far it could go. They also saved a lot of money by just analyzing the protein parts, which could help a lot of people.

Weather Effects Walruses?

Weather Effects Walruses?
As the whole world freaks out about global warming and what it is doing to the penguins and Indian tribes of the arctic, no one lends a thought to the Pacific Walrus. As the ice caps melt on the water, the walruses, along with polar bears and other arctic creatures, crowd together on the small pieces of land. While, it is obviously not good for the walruses to be on the land to start with, the huge crowds make the land a tight squeeze. When all the walruses are packed into such a small space, entering the water to hunt can be extremely hard for them. What commonly happens is that once one walrus makes its way to the water, another follows, then another, then another, and next thing you know there is a huge stampede of walruses rolling down the side of a hill.
The ice caps melting has been a huge debate ever since Al Gore released “An Inconvient Truth.” Some people blame it on people and work to reduce their carbon footprint, while others claim it is just a flux in the weather and the earth will figure it out on its own. One of the biggest problems with the walrus stampedes is the death toll. Too many walruses cannot make it into the water fast enough on the land and are crushed under the weight of the other walruses. The Pacific Walrus was just recently relieved from major hunting pressures and there are not as many of them alive as there should be. The extinction or endangerment of the Pacific Walrus would be horrible for the world’s ecosystem, as is the extinction of any other species.

At first I was quite amused by this article. It seemed like a slightly ridiculous article until I read it. It is actually a very important issue relating to climate change that I had never thought of before. It made me realize that more than just the polar bears are affected by this issue and that many other species could be affected.

The Shell Super Ship


Although a final decision has not been reached, the oil company Shell is considering purchasing the largest ship ever built. At 600,000 metric tons and 480 meters long, it is nearly 3 times the mass of the world’s largest passenger ship. The reason for building this will be to reach oil fields that used to be too far out to sea to access. It size will also allow it to pass through extreme weather, such as typhoons unaffected. As of now, oil platforms are not mobile, and as such, become obsolete when their oil fields run dry. This ship however, could simply move to another site.

This could have an impact on peoples’ lives in an indirect way. While most would never see it, they could unknowingly pump their car full of gas that was reached using this ship. If we were able to reach new oil fields, it could also reduce the price of gasoline, which everyone would notice.

I have mixed feelings about this news. On one hand, I am always excited about new engineering marvels and new ways of doing things. On the other, would rather see the money being spent on this go to alternative fuels so we wouldn’t be using up a limited resource and polluting our atmosphere.

New Strategy For Mending Broken Hearts?


By Samuel Mann


Bioengineers have just discovered how to grow heart tissue made of heart muscle cells called cardiomyocytes. The biomedical engineers at Duke's Pratt School of Engineering have created a "patch" of heart tissue that exhibits the two most important attributes of heart muscle cells; the ability to contract and to conduct electrical impulses. Mouse embryonic stem cells were used in the bioengineering project and this is an important first step to growing living, working heart tissues.

The researches grew cells in an environment much like that found in natural tissues. They used a gel composed of blood-clotting proteins to strengthen the cells and allow them to form a three dimensional structure. Additionally, the researches also found that the cardiomyocytes grew best only when "helper" cells, known as cardiac fibroblasts, were also present. The cardiac fibroblasts are present in 60% of all cells in the human heart and thus allow the heart cells to grow correctly. When tested, the cardiomyocytes were oriented properly by the cardiac fibroblasts and were thus able to contract like normal heart muscles. While this is a step in the right direction, progress still needs to be made to create blood vessels that can sustain the tissue. Hopefully these patches of heart muscles can be produced in large amounts quickly enough to be used for therapeutic restoration of damaged heart tissues due to disease and heart attacks.

Whether people love the ethics of it or not, stem cells are the future of medicine. Over the decades medicine has progressed to smaller and smaller levels within the human body. Inoculations were the first microscopic application of medicine into humans. Antibiotics, penicillin, and blood transfusions took science into the blood and tissues of our bodies. Now, stem cells can take us even deeper to combat diseases that affect us down to our very cell structures. I think the most amazing, and somewhat beautiful, part of stem cell research is that scientists actually use human-made cells. Stem cells aren't some sort of genetic product. Rather, stem cells occur naturally as a vital aspect of human development and growth. Stem cells are meant to be used to create all the cells in the human body and now scientists are beginning to harness these amazing cells to create tissues needed to fight disease. The possible benefits of stem cells and biomedical engineering seem endless and are opening new doors of science and medicine. A whole new era of medical technology is being born right now.

I am very excited about this article. For one, it is really cool. Scientists are actually growing working heart muscles! How cool is that?! I bet I will be alive to see the first fully functional human heart be made by scientists. Second, listen to the title, "Biomedical Engineering." Doesn't it just send shivers down your spine at the sound of its auspicious and high-tech name? Remember when heart transplants were the cool thing? Well now it's bioengineering. Not only am I taking AP Biology this year in high school, but I am also thinking of a career in the medical field. I was thinking about radiology, and still am, but this article has opened my mind and imagination to the possibilities of being a bioengineer.

P.S. I made that GIF. XD

Riding on Through



Riding on Through History

By: Lindsey E. Horton

Almost everybody can enjoy watching a horse run. Then again, almost everybody also enjoys solving a good puzzle. Well, it just so happens that there's a mystery that ties in both of those. Where did horse domestication originate? Now that's something worth solving.

It's now being suggested by new archeological evidence that horses were domesticated up to 5500 years ago by the Botai Culture of Kazakhstan. In present day America, horses are more of a pet to have, for riding, and for giving little girls their first love. It turns out though that to the Botai Culture, horses were much, much more. Horses were used for riding, of course, but surprisingly they were also used for food and milk! There is evidence found that suggested that people would actually drink horse milk, like we drink cow milk today. The bone structures of the horses from 5500 years ago show that they were very similar to the horses that later showed up in Europe, and to wild horses. This tells archeologists that the early people selectivley bred their wild horses for physical attributes, and to emphasize the attributes through breeding.

Through new techniques, archeologists were able to find three individual lines for early horse domestication. It was around the fourth melenium that the Botai Culture started to domesticate them. The archeologists also used a very interesting technique called "bit damage" which is caused by horses having been harrnessed or bridled, and a bit would leave a mark. This technique also supports the fact that horses were ridden back then. This early culture used something called a "thong bridle", that is shown on the image to the right.
Even more interesting, using lipid residue analysis, archeologists took a look at Botai pottery, and found that to make the pottery, people used horse fat. Through this pottery they found that people also drank the mare's milk and would let it ferment to make an acholohic sort of drink called "koumiss". They still do this in Kazakhstan. Horse tradition runs through the viens of Kazakhstan's history, very far back. Well, as far back as 5500 years ago! The steppes of Kazakhstan were plentiful with wild horses back then, and hunting them was common. It was also a great oppurtunity for the culture to get to know the equines, and how they behaved. Horses were shown to have been prefenced for adapting to the Botai culture over cattle and sheep. Even more amazingly, horses were shown to have been able to graze year round, and adapted to the harsh winters so that they could eat the grass through snow.
This discovery has a great impact on our scientific community. Scientists thought that horses were only domesticated about 4000 years ago, and this shows that they were off by quite a bit. This will change how scientists think about earlier cultures, and what they were cabable of. An impact that I predict is now that one solid fact is to be questioned, that scientists will start questioning other "known" facts about earlier civilizations, or question closer the source in which the evidence came from.
I picked this article because I love horses, and history. This seemed like an article that combined both. I was in AP world history last year, so I got a new pair of glasses, as you might say, to see history through. It's amazing to me to see how an early culture so new could make use of such a powerful and majestic resource. I also like to see how the relationship that humans and horses have today has developed through history, including the origin. I have a mare named JJ, so understanding the where the relationship between horses and people came from, and seeing how useful horses are, can really help me to bond with her better.

Swine Flu Vaccine Works in Children

Anna Dye
September 22, 2009
Physics

Studies of the new swine flu vaccine were released this week. In the study, kids aged 10 to 17 were injected with the vaccine, and then the number of antibodies in their bloodstream were counted ten days later. Of the 600 kids tested, around 76 percent had enough antibodies to be considered immune. The other 24 percent were expected to create more antibodies over time. Younger children, 6 months to 9 years, were still treated, but not as well as the older children and it’s recommended that they get a second shot about twenty days later. The second shot is also recommended for people who have never had a flu shot. A nasal for of the vaccine will also be provided, but not recommended for children under 2 or people with asthma.
For months, swine flu has been a scary topic. People go to the hospital for something as little as a sore throat, just in case it’s the dreaded swine flu. With a functional vaccine available to everyone, hospitals will be able to care for the truly sick much easier and much quicker. Schools will also be able to stay open if a student contracts the virus where as they would have had to close just months ago. Science has become very quick in just the past twenty years; before it would take way too long for a vaccine to be formed where now it takes just a few months. Maybe in the future, vaccines can be created before an epidemic is created.
I am really excited that there is a vaccine. While I will most likely not receive it, my brother (who has virus induced asthma) and grandma will be able to. This vaccine can save many, many lives. I am so amazing that this was created so quickly, and that it will be out even quicker.

New Species Discovered On Whale Skeletons

Sam Mann
Physics, Period 8
Science In The News



Death has brought new discoveries of life. When a whale dies and sinks to the seafloor, it becomes food for an entire ecosystem. Nine new species of bristleworm were recently discovered by scientists at the site of whale cadavers on the ocean bed. The bristleworm is a type of earthworm. They are so well adapted and specialized to eating dead whales that they couldn't survive anywhere except where dead whales come to rest. The bristleworms actually use a root system to attach themselves to the whale's bones while they feed on bacteria that quickly form on the whale skeleton.

Whale carcasses are a very unpredictable source of food. Whales are not abundant and knowing when and where one will die is impossible. However, did you know that a whale's carcass offers the same amount of nutrients that normally sink from the surface to the seafloor in 2000 years!? After sharks and hagfish pick the body clean of the meat, various other organisms come to feast on the skeleton.

The discovery of nine new bacteria-eating worm species in the ocean may seem to have little social importance. However, this discovery goes to show that there are many species still unknown to mankind. Scientists are finding new ones everyday but it is predicted that there are millions of species still yet to be discovered. Additionally, these nine new species are nine more species of organisms that are being threatened by global warming and humans. If global warming or over-exploitation of whales eventually causes the whales to become extinct, there goes the nine species of bristleworms with them. Sure, they may just be little worms, but the fact remains that the oceans are a very diverse place and are very fragile. Saving our earth from the current biodiversity crisis doesn't allow for even the smallest of organisms to be overlooked. Did you know that prokaryotes, organisms so small that they don't even have a cell nucleus, are used by people to detoxify the earth from man made chemicals? Even the smallest of organisms can offer environmental services to mankind. The point is that society should be aware of the many different types of species, big and small, that are being overlooked and threatened by our actions.

My personal reaction is that of curiosity and interest for our new worm friends. It is amazing that they have adapted to be able to subsist on the arbitrary and random occurrences of whale carcasses raining down from the upper levels of the oceanic biome. I took a fancy to this article because I am currently taking AP Biology. My summer homework was to read all about the various biomes of Earth and its many, many inhabitants. I learned that these worms are called benthos and they reside in the benthic zone of the ocean. The whale carcass is considered detritus which the bacteria eat, and the bristleworms are primary consumers that eat the bacteria. I will always be keeping an eye out for more of earth's species to be discovered and added to the biodiversity of life on our very special planet.

Get Smarter By Computer Games?



Get Smarter By Computer Games?

By: Lindsey Horton

Usually our parents have to tell us to stop playing computer games. Yet recently, scientists have reason to tell us that we might as well make them a nightly part of our homework. Well, perhaps not every computer game, but on in specific, called "Tetris". There is evidence to show that playing this game for up to 1.5 hours a week, for three months, that the grey matter in your brain will grow larger. The gray matter in your brain is the area that processes information, by brain cells and capillaries. 15 adolescent girls took the experiment of playing the game for 1.5 hours a week for three months, and their area of their gray matter in their brains were seen to grow larger. They were compared to other girls who, over the three months did not do the tetris, and whom showed no growth in size for their gray matter. The 15 girls that were in the study were chosen because they may not have had their gray matter affected as boys might, who stereotypically play coordinated video games more. The 15 girls began as novice players, and soon they became very experienced. Scientists suggested that the cause for the growth in grey matter is because the brain is learning to communicate different areas of itself that it hadn't before. After the three months, that communication becomes typical of the brain.
The social impact of this discovery on how to increase grey matter, an area crucial to planning complex movements, could be the increase in assigned computer use in school. Perhaps game time, which could add up to 1.5 hours a week, could be scheduled in a classroom. A teacher may perhaps assign 18 minutes a day, just like they typically assign SSR time. Another social impact could be more encouraging of computer games at home for boys, and girls as well, from their parents who would otherwise say that the computer is off limits. The last possible social impact is that researchers may do the same experiment with other games, and see if grey matter can be grown further quicker. This could mean that perhaps American soldiers could use this tactic is is was developed enough, and aim weapons better, or learn ducking moves better. 
I though that this article was very interesting because I am always very interested on how the brain evolves and works to adapt to it's surroundings. I think that this example is just one of many that attests to the fact that the brain is an amazing tool, unlike any other. I possibly want to be a cognitive scientist when I grow up, so this article particularly stands out to me.

Rock Solid Planet

Beyond the outer limits of our beloved solar system, Milky Way, there lies a planet not much different in make up than our own. To reach this far away planet you must travel for 500 light-years, dodging all the fiery balls of gas that light the night sky. The name of this far away planet is COROT-7b and the similarities in the compositions of Earth and COROT are phenomenal. Although this new extrasolar planet is much too hot to sustain life it still excites scientists and encourages them to believe that life in space is possible. In this article you learn that COROT is likely made up of a silicate mantle and an iron core, just like earth. (Didier Queloz of the Geneva Observatory in Switzerland.) Queloz team had announced that they found the planet in February of this year and were able to pin down the size, which is 1.8 of Earth’s diameter, based on the shadow it creates against its star when it periodically passes over the front of it. The last super adrenaline pumping fact in the article states that in the most recent mass measurements of the planet they have found that it has an average density of 5.6 grams per cubic centimeter, which is almost identical to that of earth!

The social impacts of a discovery like this are unbeknownst because scientists know that this new planet, dubbed COROT-7b by Queloz’s team, cannot maintain life due to heating issues. So, what will this discovery do for the world? That is what we must keep digging into and uncover.

My personal reaction to this discovery is one of disbelief. I cannot fathom how it is that we have the technology to send probes outside of our solar system, into the unknown regions of space and find, let alone measure, a planet. It almost makes me think that maybe the world will end up like Star Trek and there will be tons of planets with people living on them throughout many different galaxies. I just can’t wait to figure out what scientists do with the information they have gained from this discovery.

Overuse of energy drinks worries health pros: Article write-up


Experts are becoming concerned about the effect of energy drinks on young athletes and students. The consumption level among high school and college students continues to increase, and more and more are drinking these high caffeine level beverages for a boost of stamina, instead of eating a real meal. Some researchers wanted the U.S Food and Drug Administration to make it a rule that warning labels must be put on all the different brands of energy drinks. However, a spokeswoman from the organization named Susan Cruzan responded by saying that they had no authorization to do that, and they have “no guidance or regulations that govern the formulation of energy drinks”, making it legal for the manufacturers to sell their products without FDA approval or testing.
So what’s the effect? Why are these people so concerned? For starters, because of the high amount of caffeine in these drinks, if they are consumed to much, the effects can become harmful and toxic. Another scientist, Kathleen Miller, reported that an ingredient of bitter orange that was found in some of the drinks was closely related to ephedra, which was banned from being in dietary supplements in 2004 because of several deaths. Although the amount of bitter orange in the recipe is probably fairly miniscule, because there is no requirement or law restricting what quantity the manufacturers are using, “we really don’t know,” says Miller. The people most concerned about are young athletes. Coaches have said that their students don’t know the difference between brands like Gatorade and Red Bull, and when they drink them both interchangeably, it creates a big problem. Patrice Radden, a spokeswomen for Red Bull, stated that their product “is a functional drink and not a thirst quencher or hydrator”, and that you need to drink lots of water when consuming it. But do the majority of people who buy Red Bull know that? It appears not. Athletes are also under the assumption that weighing less, drinking, and eating less will improve their overall sport performance. A 17-year-old girl was reported to have finished a race and then collapsed at the finished line, and had to be transported to the hospital. Prior she had been complaining of fatigue and chest pains. The doctor who treated her, Eric Small of Mount Sinai Medical Center in Manhattan, discovered that instead of eating breakfast in the morning, it was common for her to drink two or three cans of Red Bull. “More youngsters are substituting protein bars and shakes for real food,” Small says.
As a high school athlete myself, I can add my own observations that there is indeed a problem with my fellow students eating power bars and drinking energy drinks to sustain their strength instead of eating three healthy meals per day. By doing this, they aren’t giving their bodies the proper nutrition and balance needed. I’ve also noticed that the tendency to not eat enough parallels with the tendency to actually overeat because the body is in need of certain nutrients. When you look at a label for a power bar, the label screams at you that it has oh-so-much protein, and that it’s just what your body needs. Take a look at the back label. Sure, it has just as many grams of protein as it states on the front, but look at the grams of fat and sugar! Not cool. Same with those good old energy drinks. Let’s look at Gatorade Rain for example. Normally the first thing that catches your eye is, “oh good, only 50 calories.” But I’m looking at that label right now, and I’m seeing yes, no fat, but also no protein. There’s sodium, potassium, and sugar. Lots of sugar. Those are the main components. I’m a strong believer in protein, whether it be nuts, meat, or beans. It’s what sustains your body for a longer time, instead of the short rush that carbs offer. Then there’s fruits and vegetables (a great fiber source), omega fatty acids (very good for you), and grains, which also provide fiber and sustenance for the day. Oh yes, and dairy products, which provide enzymes for better digestion. So those energy drinks are okay once in a while, just do your research. Make sure what you’re drinking is safe and will provide your body temporarily with what it needs. Don’t forget H2O! The average high school student should be drinking at least 8-9 cups of water per day. Have I made my point clear? I agree completely with what these experts are saying. People need to know what it is that they’re eating or drinking, and the effects it can have. I also believe that students need to be encouraged by parents, coaches, and teachers to eat healthy, regular meals, and that families should make the time to eat together. In sports, coaches should take more time to talk to their athletes about the proper nutrition that they need. If awareness is increased, I hope that it will be a step towards increasing better well-being for everyone, both young and old.

Schelle: Haha, I think I got too carried away, this article was really interesting. I couldn't post it as a comment to your post because it was too long :P Oops.
